THE DURA COMPANY, OF TOLEDO, OHIO, A CORPORATION OF OHIO WINDOVT REGULATOR Application fi led February 23,1926. Serial No. 90,105.

The invention relates to window regulators and has for one of its objects the pro vision of mechanism for actuatlng a closure.

having one of its elements formed by an ele ment of the frame in which the closure is movable, thereby reducing the number of parts and also the cost of manufacture. Another object is the provision of a frame in which the window is movable including a panel forming a wall of the chamber for receiving the closure when moved from its open position, this panel also constituting an element cooperating with a rotatable element of the mechanism for actuating the closure. Further objects of the invention reside in the novel features of construction and combinations and arrangements of parts as more fully hereinafter set forth.

In the drawings Figure 1 is an interior side elevation, partly broken away, of a vehicle door embodying my invention; V

Figure 2 is a cross sect-ion on the line 2-2 of Figure 1.

Heretofore it has been customary to mount a window regulator upon an element such as a lock board of a frame in which the closure is slidable from closed to open positions, the

frame element being used merely to support.

and position the window regulator. With my invention the frame element forms an element of the window regulator thereby re ducing the number of parts and reducing the cost of manufacture.

In detail, I have shown my invention as applied to a vehicle door 1 having theopening 2 in its upper portion and the chamber 8 in its lower portion. This door is of the all-steel type and the inner wall of its chamher 3 is formed of the sheet 'steelpanel 4i.

5 is the closure slidably arranged in the door frame and adapted when in its upper position to close the opening 2 and when lowered to enter the chamber 3; 6 is a lifter arm suitably connected to the closure 5 as by means of the roller 7 at the outer end of the lifter arm engaging in the channel 8 which is secured to the lower edge of the closure. For swinging the lifter arm there is in the present instance the external gear 9, to which the inner end ofthe lifter arm is rigidly se- I cured. This gear is xjournaled upon the crank 10 of the shaft 11, which latter is journaled in the boss 12 of the bracket 13 having a plurality of arms rigidly secured to thepanel 4. The inner end of the shaft '11 may have secured thereto a suitable operating handle. To compel rotation of the external gear 9 upon rotation of the shaft 11, I hawe formed in the panel 4C the internal gear 14, the teeth of which are adapted to successively mesh with the teeth of the external gear when the latter is carried. through its circular orbit. 7

With this arrangement it will be seen that the panel, in addition to forming a wall of the-chamber for receiving theclosure, forms an element of the mechanism for actuating the closure. It will also be. seen that in addition to reducing the number of parts and the cost of manufacture, the space at the outer side of the panel and within the chamber occupied by the closure actuating mechanism is materially reduced, thereby permitting of the use of a thinner door having a narrower chamber.

While I have shown one embodiment of my invention it is apparent that other embodiments falling within the scope of the appended claims may be used.

What I claim as my invention is:

1. The combination of a frame having an opening and a chamber adjacent to said opening, a closure for said opening movable intosaid chamber and mechanism for actuating said closure including a member forming an element of said chamber and also an element of said actuating mechanism.

2. The combination of a frame having an opening and a chamber adjacent to said opening,- a closure for said opening movable into said chamber and mechanism for actuating said closure including a panel member forming a wall of said chamber and also an element of said actuating mechanism.

3. The combination of a frame having an 2 opening and a chamber adjacent to said opening, a closure for said opening movable into said chamber and mechanism for actuating said closure including a gear and a member forming an element of said chamber and also a gear for cooperating with said firstmentioned gear.

4. The combination of a frame having an opening and a chamber adjacent tosaid opening, a closure for said opening movable into said chamber and mechanism for actuating said closure, including an external gear and an arm connected thereto and a panel 10 forming a wall of said chamberand also an internal gear for meshing with said external gear. 1

5. The combination of a frame having an opening and a chamber adjacent to said. opening, a closure for said opening. movable into said chamber and mechanism for actuating said closure including a rotatable memher, a member forming an element of said chamber and also an element for cooperating with said rotatable element and a'support secured to said last-mentioned memberfor carrying said rotatable member.

6. The combinationof a frame having an opening and a chamber adjacent to said opening, a closure for said opening movable into said chamber, a lifter arm connected to said closure, an external gear carrying said lifter arm, a member forming a wall of said chamher and also an internal gear for meshing V with said external gear, a bracket upon said last-mentioned member and a shaft journaled in said bracket and having a crank on which said external gear is journaled.

In testimony whereof I afiix my signature.
